To all whom it may concern:

Be it known that I, MACK J. HEALY, a citizen of the United .St-atesfresiding at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Ring- Shields for Glass-Drawin Apparatus; and I do hereby declare lthe lollowing to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to an improvement in ring shields for glass drawing apparatus, and is designed particularly as an improvement on the construction disclosed in my pending application No."64:8,371, filed September 8th, 1911.

In my pending application the ring shield gage either the inner or outer face of the floating ring at the top of the latter and form an upward extension of continuation of the same.

The object of the present invention is to, provide means depending at intervals from the ring shield, for engaging and centering the floating ring, whereby, when the parts are in operative position, there will be a space between the shield and floating 'ng, thus avoiding the cooling effect on the cating ring,- that is produced by the contact therewith of a water cooled ring, and also permits'suiiicient heat to enter between the rings to fire polish the cylinder.

With these and other objects in view, my invention consists in a water cooled shield ring having a plurality of depending fin gersadapted to engage and center the floating ring, and hold same in position under thedrawing opening.

My invention further consistsxinrcertain details of construction of the ring shield as out the claims.

Inthe accompanying drawings Figure 1 Lrepresents the ringf'shield composed of plates 4 riveted or. otherwise secured respectively to the inner and outer edges of said ringsjl and 3, thus forming a hollow cross, section, and of a size sufiicient to shield Specification of Letters Patent.

and protect the cylinder being drawn; Located Within the ring shield 1 is the circular or endless pipe 5 which is perforated so as to discharge the water into the hollow ring shield, preferably connected with a plurality of water inlet pipes 6. A plurality of outlet pipes 7 communicate with the interior of the ring shield. The several inlet pipes 6 and outletpipes 'i are Widely separated so as to supply the necessary volume of cold water at differentpoints, and to carry it off as fast as supplied and before it travels sufficiently far, or remainssufiiciently long, to become highly heated. v4 The several inlet pipes 8 are connected at their tops to a cross pipe 6 which receives its supply from a single pipe 6*, and the outlet pipes are similarly connected with a cross pipe "1' communicating with a single outlet pipe 7". The ring 1 thus constructed, is provided with a series of eyebolts 8, projecting from its top to which'the supporting and elevating and lowering chain or cables areconnected, and-also'wlth a plurality of fingers 9 projecting downwardly below the bottom of the shield so as to engage the top portion oi the floating ring 10,

By means of the bendsor elbows irrthe fingers, the shield ring isprcvented from contacting with the floating ring thus providing a space for the entrance of sufficient heat to impart a fire polish to the cylinder. Again, by this construction. the ring shield may be of the same diameter'as the floating ring, and when the parts are in operative position, the floating; ring will be held stationary by the engagcment'therewith of the fingers. There being no contd ct between the cooled ring shield and the hot floating ring thelatteuwill not be in iured by the contact or coolingeitect'resulting from contact.

' Iti's evident. th'at ilany slight changesto the exact construction and arrangement of parts shown and described. but

what I'claim-ns new andkdes'ire to secure by Letters-Patei1t,is:--

1. A ring shield for glassdrawing; apparatus having a piurality ct depending iin= gers to engage and center the i ring.

2. A. ring shield this: drawing appa- 105 Having fully described my invent-ion ratus having a plurality of fingers depending from the lower edge of the ring to engage and center the floating ring.

3. A ring shield for glessdrawing apparatus having a plurality of bent fingers adapted to engage and center the floating rm '-1 4? A ring-shield for glass blowing apparatus having a plurality of fingers depending from same the latter being bent to engage a side face of a flouting ring.

A ring shield for glass blowin apparatus having a plurality of fingers depending from the lower edge of same, the said fingers adapted to engage a side face of a floating ring.

6. A hollow ring shield comprising top and bottom rings and side plate connecting W. O. PURPLE, F. P. GEQGHEGAN.
